If anyone has physical access to your device, you've got other problems than just wifi history.
Seriously. :-)
I have a little Chromebook I got for listening patiently to a 30-minute spiel from Google about using Google Cloud Services a few years ago. It hasn't left my office all that time, except to come home with me at the start of the Great WuFlu Episode. So my WiFi history has exactly two locations in it.
Pretty boring.
